Symbiont is a framework that allows you to describe your application in terms of activity and page definitions. Those definitions can then be referenced by test libraries using the DSL that Symbiont provides. The DSL allows web elements to be proxied to a driver library. The DSL provides a fluent interface that can be used for constructing test execution logic. This fluent interface promotes the idea of compressibility of your test logic, allowing for more factoring, more reuse, and less repetition. You can use Symbiont directly as an automated test library or you can use it with other tools such as RSpec, Cucumber, or my own Lucid tool.
